Thev plates A', on account of their dovetail engagement with the bars Apare securelyheld oir. the latter, and can only'bearemoved.byunthreading. them in an axial direction. The platesiB", on" the contrary, can be removed by simply lifting. them on. their supporting-1iseats.` Ricans-hereinafter described are however provided for locking plates of both kinds A3 and.y p'osition,..when" once ythe composing has' beencompleted;

gitudinal grooves t3betwmsltheafails#and the 66" beyondfwhicnthey protect; sonas tof :superpose themselves on the surface of the adjacent elements, thus masking the junction lines, While at the same time they lock the elements in position. Thus each element A, along the edge adjacent to a companion element or to the frame 9', and along its parallel edges perpendicular to the first one, is provided with bosses I4 overhanging the said edges, as shown in Figures 1, 3, 4 and 5. Each element B on the other hand is provided along only one of its edges adjacent to another element B with bosses I4, as shown in Figures 1, 6, 7 and 8. Thanks to this arrangement each element B' is locked in its place by the projecting bosses I4 of the adjacent elements A. and also by the bosses I4" of the adjacent element B, which prevent it rising from the plane of the chase, while at the same time leaving it free to slide axially along the grooves I3.

At the end of each row of space-line plates A is ranged a special terminal locking plate A", shown in detail on :a larger scale in Figures 11 and 12. This locking plate A", which is not provided underneath with the dovetail-shaped projections I of the plates A', but merely with alignment projections 10, is not engaged by axial sliding in the dovetail-shaped groove I of the bars A, but is applied flat thereto on these bars, as the plates B' are applied to the bars B. The plate Al is provided at the rear with a revolving bolt l5, with its end I5 bevelled, rigid with a disc I6 rotatably mounted in the body of the plate and adapted to be controlled from the outside by means of a key. The locking plate A presses upon the bar A at the end of the row of plates A while the bolt l5 is in the position marked in dotted lines in Figure 11. Then, upon rotating the disc i6 through 90 degrees, the bolt l5 is carried into the position shown in full lines in Figures 11 and 12. The ends I5' of the bolt then engage in the dovetail-shaped groove I in the bar A, and the plate A remains locked in place, together with all the plates A in the line.

The type characters Il, which may also be made of a phenolic and thermoplastic resin or other plastic material, are xed at upon the bosses I4 of the plates B by means of shanks ll with which the type characters are provided at the back. These Shanks H', threaded into holes 14 provided in each plate in correspondence with the bosses I4, are then up-set or riveted over hot at their ends, thus forming a retaining head 11.

It is not essential that the plates B should all be of the same breadth. Thus for example for the letter I and for the numeral 1 a minimum breadth is suincient, but for M or W" a much greater breadth is required, and for other letters and numerals an intermediate breadth. All this will be clear from Figure 1.

To eiect the composition, and bearing in mind that the space-line plates A' always remain in position on the chase, all that is necessary is to remove the terminal locking plates A", shown in Figures 11 and 12, in order to provide a clear space for applying, one at a time, plates B' with the type characters relating thereto, then sliding them axially along the bars B until they completely fill all the lines. When the composing has been completed, the plates A" are replaced, and the entire mosaic remains locked. If it is desired to remove or change one or more of the type characters of the composition, rst the locking plates A" of the space-lines adjacent to the line in question are removed, and then the plates A and also the plates B are displaced by sliding them towards the right so as to isolate the plate '4 B' bearing the type character to be changed, for instance the N in Figure 1. When the removal and substitution have been effected the entire assembly of plates is closed up again, and the plates A are replaced.

With the device described above it is possible to set up announcement or advertisement panels which can be changed or adjourned as required, and which present an agreeable appearance, with great clearness and legibility.

It Will be readily understood that the invention is not restricted to the particular arrangements hereinbefore described and illustrated, but that modifications may be made therein without going outside the ambit of the invention.

I claim:
